I'm guessing here but I think that one end or the other is overloaded and there's a backup of traffic. The Cisco then holds the data for x period of time and it either gets through or it dies there....

But I'm certainly no expert. I'm trying to remember the kinds of things that happened back when we were still running a 56k data link to the net and had it stuffed completely full.

I am seeing some errors on a client's network and I need some
expertise.  Here is the output from the Cisco:
cdg-gate#sh interfaces FastEthernet0/0

FastEthernet0/0 is up, line protocol is up
 Hardware is AmdFE, address is 0030.8558.8060 (bia 0030.8558.8060)
 Internet address is
 MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
    reliability 255/255, txload 1/255, rxload 1/255
 Encapsulation ARPA, loopback not set
 Keepalive set (10 sec)

 ARP type: ARPA, ARP Timeout 04:00:00
 Last input 00:00:04, output 00:00:00, output hang never
 Last clearing of "show interface" counters 00:01:28

    9064 packets input, 9837705 bytes
    Received 1 broadcasts, 0 runts, 0 giants, 0 throttles
    0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
    0 watchdog
    0 input packets with dribble condition detected
    8003 packets output, 1130789 bytes, 0 underruns(0/0/0)
    0 output errors, 0 collisions, 0 interface resets
    0 babbles, 0 late collision, 19 deferred
    0 lost carrier, 0 no carrier
    0 output buffer failures, 0 output buffers swapped out

Note the "deferred" output packets.  Can anyone provide some input
on what would cause this?  The T1 side is not seeing any errors at
all.  Network is:

T1 -> Cisco -> SonicWall -> Switch

The SonicWall is configured as a bridge and has been a source of
good income for me (lots of time "fixing" it).  I suspect the
problem is the SonicWall, but not certain.  I plan to bypass the
SonicWall, but wanted some input from those more experienced with
Cisco as to what I may be able to do to see what is happening on the
network from the Cisco's perspective.  Thanks for your help.
